Hello aspirant,

According to my personal experience, I would recommend you to study 3 subjects - Physics, Chemistry and Mathematics in your entire day. You can do so by dividing your time in 3 phases like you can prefer to revise one of the subjects in the early morning, second subject in the evenings, and the last subject at night.

One effective strategy for this, that I would recommend, would be that you must study that subject in the early morning which you find the most challenging or difficult, as you are very energetic in the morning. And the second difficult subject in the evenings or during afternoon, while the easiest subject in the night, when you are lazy or feeling tired. By doing this, you will be focused and concentrated at your studies without losing any interests in your studies.

And I think it will be Silly to mention the Importance of Time management and productivity tips in this answer. You can make your own Time Table which you find to be very effective and can start working accordingly. This was my strategy.
